The Mini Personal Tracking System receives signals from twenty four satellites orbiting the earth. With this information, the Mini Personal Tracking System can precisely calculate its own position anywhere on the planet to within fifteen meters. The Track Stick records its own location, time, date, speed, heading and altitude at preset intervals. With over 1Mb of memory, it can store months of travel information. The Track Stick's micro computer contains special mathematical algorithms, that can calculate how long you have been indoors.
